GRAIN-WEIGHER.

SPECIFICATION forming part of Letters Patent No. 443,933, dated December 30, 1890.

Original application filed February ll, 1890, Serial No. 339,967. Divided and this application tiled July 28, 1890. Serial No.

360,246. (No model.)

To all whom t may concer/t:

Be it known that we, CHARLES H. COOLEY and Finnois H. RICHARDS, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful lmprovenients in Grain-lVeighers, of which the following is a specification.

This invention rela-tes to grain-wcighers, and has for its object to furnish an improved grain-bucket mechanism.

This application is in part a division of our prior application Serial No. 339,967, tiled February 11, 1890.

In the drawings accompanying` and forni ing a part of this speciiication, Figure 1 is a side elevation, partially in section, of a grainbucket mechanism embodying our present improvements. Fig. 2 is a front elevation of the saine, partially in section. Fig. 3 is a horizontal section through a part of the grainbucket in line a a, Fig. 1. Fig. -1- is a plan view of one end of the bucket-closer. Fig. is a vertical transverse section through the lower part of the grain-bucket and bucketcloser in line Z) l), Fig. E?.

Similar characters designate like parts in all the figures.

The grain-bucket consists otl a buckettraine F, the outer walls 112 and 1&3, and the partition-wall 111-, suitably liked i n thebucket. The frame F has a division-bar 145 separating the discharge-space into two dischargespouts 3i and 3G, respectively. On said bar are formed abutinents 300 and 302 on either side ot the lower edge of said partition-wall 1li for holding said wall. in place, this wall being usually' made of comparatively thin sheet metal. The frame F has extending around the upper edges thereof a suitablyformed rim, as 301, to which the outer walls M2 and 143 are secured by rivets 38, as best shown in Fig. 5. As seen in side view the line between said frame F and the side walls is not a straight one, but rises from the sides toward the center, the intermediate space being occupied by the vertical wall 150, which is a part of the traine F and carries the hubs 12, in which are suitably lifted the bucketpivots 1i. The walls 142 and 143, respectively, are cach formed oit a single piece ot metal extending across the front and rear sides, respectively, of the bucket, the ends ot said plates or walls being bent at the back corners, as at SOi, 306, and 30S, to form the side walls 112, 113, and 113", respectively. These side-wall portions of said plates 112 and 143 meet at the line ot the partition 141-, and are joined by rivets, as 30,100 the ribs 110, which are fixed at their lower ends to the bucket-traine F, as best shown in Fig. 5. On the inner side of said ribs grooves, as G3, are formed for receiving the edges of the partition-wall 1li. By this system of construction the grain-bucket is composed of few pieces of light weight rigidly united to one casting F, constituting a traine-work therefor and carrying the pivots thereon. In practice the said outer walls and partition-wall are formed ot sheet metal suitably shaped, and ribs 140 and 141 are formed oi' suitable malleable casting or of rolled bars suitably shaped. By extending the frame F upward to torni the walls 150 and by placing the pivots thereon these are brought high enough in the structure to secu re the proper degree of oscillation both of the upper and lower ends of the bucket without placing the pivots upon the sheet-metal walls, it having been found in practice that a grain-bucket torined wholly of sheet metal or having the pivots secured on the sheet-metal portion thereof is subject to too great flexure to be reliable in. operation.

By means of our improved construction o1' the bucket both lightness and ample rigidity are'readily secured.

For properly limiting the movement of the bucket suitable stops are provided, as herein described, and for holding the bucket in its respective positions (ot which one position only is shown herein) suitable catches are also provided. The bucket is supported in the hangers 16 and 18, respectively, by the said pivots 12, which iit bearings formed in the hangers, as indicated in the drawings. The bucket-catches 4.0 are secured to the side walls of the bucket by screws 303, which pass through the said stops and side walls and usually have check-nuts 305 (see Fig. 2) on the inner ends thereof. Said screws also should pass through the fianges of the ribs v 140 and 141, thus being connected by said ribs with the rigid frame-work I1" of the bucket. For engaging said bucket-stop catches we lnay use the latch-levers 42, which are pivoted to the hangers at 43 and have the latch-catches 41 secured thereto by screws 44, all as more fully described in the application of F. II. Richards, Serial No. 341,499, filed February 24, 1890, to which reference may be had for a more complete description thereof. It will, however, be understood that other well-kn own forms of bucket dctent-catches may be employed in connection with the improvements claimed herein.

To the lower ends of the hangers 16 and 18 is secured thebucket-closer L, which, as shown in the drawings, consists of the two oppositelydisposed closer-plates .and 76, respectively, which are connected together at the ends thereof by a cross-bar, and are fixed to the hangers by means of the screws 307. As shown herein, said closers are set relatively to the axis of the bucket, according to the invention described in the application of C. I-I. Cooley, Serial No. 358,643, filed .Iuly14, 1890, t0 which reference may be had for a more particular description of said feature.

Since the bucket-closers 75 and 76 are substantially the same, a description of one of them will answer for a description of both. The closer-plate 76 is set at some distance below the mouthof the spout 36, as shown in Figs. 1 and 5, so that grain of the kind to be weighed in the machine may pass through the space 8 between said parts. The lower edge of said plate, however, is closed by the adjustable plate 58, as set forth in the prior application of 0.11. Cooley, Serial No. 338,818, filed January 31, 1890. Above the outer edge 309 ofthe spout 36 the plate 7 6 has an abrupt vertical wall 310, and is continued beyond said wall, as at 311, to another vertical wall 312, forming the upper and outer edge of the closer, on which upper edge a stop 313 is provided to limit the bucket movement by striking a corresponding stop 314 on the frame F. Over the portion 311 of the closer 76 and on the side wall of the frame F there is formed a downwardly-projecting rim 315, between which and the edge 309 of the spout 36 there is formed a groove 316,\vhich co-opcrates with the vertical wall 310 of the closer to prevent the grain on the first filling of the bucket from scattering out between the closer and said spout. The grain coming down through the bucket and spout strikes the closer 76 and is scattered violently, some of it tending to pass between said parts and escape. This will be understood by means of the dot-ted line d and the arrow adjacent thereto -in Fig. 5. A kernel of grain in passing down, as indicated by said arrow, strikes the bucket at 5 and glances off against the closer at 7, whence it glances upward into the groove 316 and is arrested by said guard-rim 315. if, however, the grain falls so as to be deflected more nearly horizontal, it strikes the first vertical wall 310 of the closer and is thereby arrested, in any case being stopped before passing` out of the bucket.

By means of this bucket construction and the described combinations we are enabled to make the space 8 suliiciently large for the properhandlin g of corn and coarse grains, and at the same time to use our machine for wheat and smaller grains, which freely pass through the spaces between the bucket and closer. In this connect-ion it should be understood that a safe and free operation of the bucket requires the spaces between said parts to be sufficiently large, so that a kernel of grain cannot possibly wedge between them, and thus block the' machine at the ends of the spouts 34 and 36. The end walls 318 and 320 of the closer L not only constitute connecting-bars for the closer-plates 75 and 76, but also act as guards for preventing the escape of the grain at the ends of the spouts.

For a description of the general operation of the grain-bucket mechanism and the manner in which the same is employedin the grain-weighing machine,y reference may be had to said prior applications.

Having thus described our invention, we
